==Key Stage 4==
===Meaning===
[[Osmosis]] is the [[diffusion]] of [[water]] from a high [[water]] [[concentration]] to a low [[water]] [[concentration]] through a [[Partially Permeable Membrane|partially permeable membrane]].

===About Osmosis===
: [[Osmosis]] is how [[plant]]s get [[water]] through their [[root]]s and how [[animal]]s gain [[water]] through the walls of the [[Small Intestine]] and [[Large Intestine]].
: [[Osmosis]] is how [[Cell (Biology)|cells]] [[Absorb (Biology)|absorb]] and release [[water]].
: [[Osmosis]] is a passive process which means it does not require [[energy]] to take place.
: A high [[water]] [[concentration]] means [[water]] with very little [[dissolve]]d [[salt]]s or [[sugar]]s. A low [[water]] [[concentration]] is [[water]] with a high [[concentration]] of [[salt]]s or [[sugar]]s in [[solution]].
: A [[Partially Permeable Membrane|partially permeable membrane]] is a [[membrane]] which only allows through certain [[molecule]]s. This is often small [[molecule]]s like [[water]] that can pass through but not larger [[molecule]]s like [[sugar]]. However, the [[Cell Membrane|cell membrane]] is selectively permeable which means it can control what [[molecule]]s pass through.
